The experiment was performed on rats that were given ethanol ad libitum for 4 weeks. After decapitation of the animals, pancreatic sections were prepared for an electron microscopy. A significant broadening of the rough endoplasmic reticulum cisterns in the vesicular cells was observed as well as the presence of nuclei with irregular outlines resulted from placation of the nuclear membrane, which is worth of attention. Such a picture suggests that the examined cells had a lowered metabolic ability.
